HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 248,906', dated November 1,1881. Application iIedvScptember 2, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. BAKER, of the city and county of San Francisco, State'of California, have invented an Improved Horse- Power; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an apparatus for applying horse-power; and it consists in a horizontal drum revolved by a vertical gear-wheel engaging with a gear crown-plate, the latter being operated by an extended lever or tongue, which is connected with or disconnected from said crown-plate by mea-ns of certain devices operated by a lever.

It further consists in the details of this construction, together with a braking mechanism by which the drum may be prevented from slipping back or stopped when necessary. A more particular description ot' this will hereinafter fully appear.

rIhe object of my invention is to provide a horse-power for lifting purposes or for driving machinery, or for both combined, as when used to hoist ore from amine, and at the same time operate a stamp-mill.

Referring to the accompanying drawings, Figure 1 is a perspective view oi' my device. Fig. 2 is a vertical section. Fig. 3 is a horizontal section. Fig. 4 is a view ofthe tongue or lever.

Let A represent the base, having ange, a, on its lower edge, whereby it is secured to the ground or to appropriate frame work. From its center projects upward the kingpost B, rigidly secured thereto, or, if desirable, the king-post and base may be cast in one piece. The king-post has a larger circumference at its base than above, thus forming au extended rim or ledge, b. Around the base of the kingpost B loosely lits a clutch ring or band, C, provided with upwardly-projecting vertical pins or lugs D. This clutch-ring C lies upon the rounded top of the base A, and is loose enough to move around the king-post. In the periphery of the cl utch-rin g C is a circumferential groove or channel, e. y

In the rear ofthe base A are the standards D', having a connecting-rod, E, tothe projecting ends of which arejournaled the ends ot' the curved clutchlever F, said lever passing forward, as shown. On each side ot' the clutchlever F are screws or bolts G, passing through into the channel e of the clutchringO.

The front of the base Ais slotted, as shown at c, to receive the upper arm ot' the bell-crank lever H, which is connected by a rod, I, to the vertical lever J. rIhe upper arin of the bellcrank lever H has pivoted thereto a pitinau or rod, K, the upper end ot' which is pivoted to the frontof the clutch-lever F.

A vertical curved rack-bar, L, retains the lever J in place. Vhen the lever J is pulled hack the bell-crank lever H raises the clutchlever F about its pivoted ends as a fulcrum, which thus raises the clutch-ring C evenly by means of the side screws, G.

Let M represent the crown-plate, provided on its outer rim with gear-teeth, as shown. It has a perforated hub, N, having at its base a circular flange or plate, O, the outer edge otl which has a channel'or groove, as shown, and is provided around the hub N with holes d. The crown-plate, with its lower plate, O, tits over the king-post B, the lower surface ofthe plate resting upon the ledge I) ofthe kingpost, and the holes cl itting over the vertical lugs D. The perforated hub N is grooved between the crown-plate M and the lower plate, O, to receive the main lever or tongue P, which is journaled about the said hub so as to turn loosely thereon. The lever P is provided with a series ot' holes or sockets, h, ranged around in a circle to correspond with the holes l in the plate O.

Around the whole device are standards or posts Z, upon the top ot' which is a track ring or tire Y. The tongue P slides up this as it revolves. It furnishes a support and bearing for said tongue and prevents it from cramping or producing great friction upon the clutchring as it is moved when released. When the ring C, with its vertical lugs D, is raised the said lugs pass through the holes l in the plate O aud into the holes or sockets h in the main lever P, thus locking the said lever to the plate O and perforted hub N, whereby, when the lever is turned, the crown-plate M will be removed.

On top ofthe crown-plate M, extending across and covering its perforated hub N, is a bracket, Q. This is secured to the top of the king-post B by screws or bolts. This plate holds the ing braking device:

n one side, toward the front of the base A, is secured the vertical standard U, to the side of which is pivoted the lever-arm V, which is connected by a rod,f, with the vertical lever \V, provided with a rack-bar, as shown.

To the upper end ot" the standard U is secured the strap X, which passes around in the grooved edge of the lower plate. 0, and is fastened to the top of the lever-arm V. Thus when the lever W is pulled back the lever-arm V is so moved 'about its pivot-point as to tighten the strap X about the plate O, and to hold it firmly to prevent it from reversing its revolution.

The operation of the whole device is as follows: When the lever J is forward the ring C rests upon the base A, and the vertical lugs D do not project to engage with the main lever P, so that, being thus unlocked, it can turn without operating the device. When the lever J is drawn back it raises the ring C so that its vertical lugs project through the holes d in the lower plate, O, and engage with the holes h in the main lever P, which so secures it that the lower plate, O, and crown-plate M will be caused to revolve together and transmit motion to the horizontal drum S. When it is desired to hold the drum in one place the braking-strap X may be drawn tight around the plate 0 by the lever YV. The horsepower is to be applied to the end of the main tonguelever P, and the connections of the machinery with the drum S so made as to allow the line of travel to be clear. The track Y supports the tongue P and prevents it from cramping. By releasing' the lever J the ring G will drop and withdraw its pins l), unlocking the main lever P, so that the horse may continue his draft without working the device. This will be useful in stopping the power without stopping the horse.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.Thecombination ofthe king-post B,cogged crown-plate M, havingr a perforated hub, N, and lower plate or ilange, t), the main lever or tongue P, secured to said hub N,and the horizontal drum S, journaled in a bracket, Q, secured to the king-post, said drum carrying a vertical gear -wheel, T, engaging with the cogged crown-plate M, substantially as and for ythe purpose herein described.

2. The king-post B, crown-plate M, having a channeled or grooved perforated hub, N, lower plate, O, having holes el, main lever or tongue P, fitting said hub and having holes or sockets h, and the horizontal drum S, journaled upon a bracket secured to the king-post, in combination with the clutch ring or band C, loosely fitting the baseof the king-post B,and provided with the vertical points, lugs,orpins D, substantially as and for the purpose herein described.
